DC INVERTER MMA WELDING MACHINE MMA-400

Main transformer users super micro-crystal magnetic material

Using single IGBTtube, quality and price is better and module IGBT.

Air passage is designed by protecting against water, dust and wind erosion, increasing the stability of machine inner working.

The fan heat diffusion effiency can be up to 100% , greatly increasing the duty cycle of welder

When working under 40 degree environment, the duty cycle is not less than 55%

The output effiency can be up to 93%, the max power factor can be up to 0.95.

Stable welding current in spite of input voltage fluctuation

With arc force and hot arc starting function, also VRD
